Euphonix Modular I/O Configuration Guide Product Description
12
For use as a local-side interface for redundant MADI-over-
Fiber, four rear-plane “positions” of 3-slots each are audio
isolated from the rest of the frame. These positions are as
follows: slots 8-10, slots 11-13, slots 14-16, and slots17-19.
Modules placed in these positions share the frames sync
and control busses.
The remaining 7 rear-plane slots (which includes the four
“reserved” slots) may be isolated from the front-plane via an
interconnect PCB located in the unit (configurable via DIP
switched, some disassembly required to access).
Connections, Power, Space, Weight
Power (IEEEx2); PSU: autosensing (100~240vAC, 50/60Hz);
input current (internal 5vDC rail at maximum load): 1.5A @
99vAC, 700mA @ 207vAC; output: 5v@12A usable power,
3RU, front-plane module space: 72HP, rear-plane space:
76HP (typical module width: 4HP/8HP), audio connections
will appear on front and rear in typical configurations.
Weight: ~5.3kg.
1.2 MADI, Control, and Sync modules
1.2.1 MM934/MM934opt MADI In/Out
General Description
The MM934 contains a single MADI I/O and optional multi-
mode fiber transceiver (MM934opt). The module features a
master sync mode that allows it to derive the master sync
source for the rack from its MADI input. MADI working
modes set via on-board switches determine how it connects
to the 32 stereo busses available on the backplane. All
settings are done from on-board switches.
Working modes (label from MADI perspective). See
Chapter 2 for cross reference between MADI I/O and audio
busses.
